The Water Impermeability and Self-repairing Performance of the Rapid Setting Polymer-modified Waterproof Mortar

Abstract

The water impermeability of the rapid setting conventional and polymer-modified waterproof mortars is systematically compared in this paper. Additionally, the self-repairing performance of the rapid setting polymer-modified waterproof mortar is highlighted. Compared with the rapid setting conventional waterproof mortar, the rapid setting polymer-modified waterproof mortar possesses better water impermeability. Furthermore, the presence of the specific reactive chemical compound is justified to improve the secondary water impermeability and thus the self-repairing property of the rapid setting polymer-modified waterproof mortar.
